Open win32diskimager executable and Select the drive letter of the microSD (very important – don’t select your C: drive. Everything in PC will be lost.). If you have doubt, go to ‘My Computer’ (or ‘This PC’ for windows 10). Insert/Remove the SD card adapter and find the correct drive letter that is getting assigned

Also Select the Image that we unzipped

Install the ‘OS’

Test the OS:

Remove the micro SD card from adapter and insert it on the Raspberry Pi (the slot is on the back side)

Connect HDMI Out of Pi to a TV

Connect Power (and optionally Keyboard/Mouse)

You will see the Raspbian OS boot up and the Pixel desktop will also come up in a few seconds. All is Well !!
